Carbon dating used evolution 100 dating site in italy
The displaced neutrons bond with nitrogen-14 (N-14) converting it into C-14.
Because C-14 is radioactive, it is unstable, and is constantly decaying back into N-14.
Many people mistakenly believe carbon dating can be used to date objects that are millions or even billions of years old.
While this doesn’t render the dating method useless, it does bring its overall accuracy into question.
How radioactive carbon is formed Normal carbon atoms weigh 12 atomic mass units, while a radioactive form of carbon weighs 14 atomic mass units, which is called carbon-14 (C-14). It is estimated that only one out of every trillion carbon atoms is C-14.
Since C-14 is so well distributed in the atmosphere, it is assumed the same ratio that is in the atmosphere will also be in an organism.
How carbon dating is supposed to work Once an organism dies, its C-14 decay is no longer being replaced by intake.

With this said, it would be worth while to check out this feedback session which does seem to suggest that there might have been an accelerated decay rate in the past, at least for the uranium-lead method.
